MOTOR-PLOW onnnmen.

Specification of Letters Patent.

Patented uly 23, 1907.

To all whom it may concern:

Be it known that we, JOHN Q. BLUE and GUSTAVUS H. MARQUARDT, citizens of the United States, residing at South Haven, in the county of Sumner and State of Kansas, have invented certain'ne w and vuseiul Improvements in Motor-Plow Oarriages, of which the following is a specification, referencebeing had therein to theaccompanying drawing.

This invention relates to mechanically-driven agricultural machines or vehicles, and it provides a'motoractuated carriage for plows and similar implements which may possess any or all oi the following advantageous features: v i

,The various parts of the machine are so constructed and arranged as to provide an implement of very substantial construction, capable of long, eflicient, and continuous service, and so organized as to be easily operable.

The machine includes means whereby the carriage is caused'to turn at the end of a furrow, or whereotherwise necessary, by operation of the main supporting-wheels, means under control of the operator being provided for readily effecting this movement.

Simple means are provided for quickly and readily throwing the actuating mechanism, as a whole or separate parts thereof, into or out of operation at will.

Means are provided whereby the tilt of the plows can be easily altered, the depth of plowing changed, and the plows lifted entirely from'the ground, any or all of these operations being capable of. performance while the machine is either in motion or at rest.

Readily operable means within easy reach of tlie operator are embodied in the machine for guiding the same while in operation.

Provision is made for changing the position of certain parts of the machine to meet changing conditions of service or different weights placed upon the carriage.

The operating-levers,- guiding-wheel, and means for controlling the motor are assembled within easy reach of the operator without leaving his seat.

The details of construction and arrangement of parts contemplated by this invention are disclosed in In the drawings, like reference characters refer to corresponding parts in the several views, of which- Figure 1 is a view showing the land side of the implement; Fig. 2 is a view, partly in section, showing the furrow side of the implement; Fig. 3 is a plan view of the implement with parts omitted; Fig. 4 is a front view of part pf the implement sho'wing the clutch and drive'device'a/one oi the clutch and drive mechanisms being shown in section; Fig. 5 is adetail View of one of the supporting-brackets; Fig. 6 is a detail top yiew of a portion of the steering mechanism; Fig. 7 is a sectional view, taken on the line x-z, Fig. 6; Fig. 8 is a sectional view, taken on the line yy, Fig. 6; Fig. 9 is a detail view'of the caster-wheel support; Fig, 10 is a detail side View of the main drive wheel; and Fig. 11 is a sectional view of the main drive-wheel.

i Throughout this application, for the purpose of disting'uishing. one from the other, the main land-wheels are designated as the supporting-wheels, the trailing wheel at the rear of the machine as the caster-wheel, the large drive-wheel on the drive-shaft as the main drivewheel, and the smaller drive-wheels near the ends of the drive-shaft as the secondary drive-wheels.

The machine includes a main frame comprisinga U- shaped member 16 which forms the outer longitudinal members of the frame and the rear cross member,'a cross-member 17 which is attached to the forward ends of member 16, and longitudinal members 18 attached to the cross-member l7 and-to the cross part of member 16.

The ma in frame is carried by supporting-wheels 19 on the land side and 20 on the furrow side, journaled on an axle 21 secured to the irame by brackets 22 attached to the under sides of members 16 and 18.

V A plurality of sets of apertures 23 are provided in the main frame-members to accommodate bolts 24 which. secure the brackets 22, in order that those brackets may be shifted to properly balance the machine for different weights and to meet other-varying conditions.

' on the land side where the land-side supporting-wheel 19 is journaled, in order that the frame may be raised and lowered and the land-side supporting-wheel may be adjusted for different depths of furrow. An operatinglever 26 for raising and lowering the land-side supporting-wheel is iulcrumed on axle 21, is attached to the crank-arm 25 near the journal of the supporting-wheel by a strap 27, and has a hand-coutrolled pawl 28 which is cooperable with a ratchet-segment 29 attached to one of brackets 22. A drive-shaft 30 is journaled in standards 31 attached to the topof frame-members 16 and 18 near the front of the machine.

The machine is driven by any suitable motor lo- I cated on top of the main frame, power being transmitted from wheel M of the motor by means of a belt32 to the main drive-wheel 33 situated at or about the center of and loose upon the drive-shaft 30. Standards 31 are of sufficient height to enable the main drive-wheel to clear'the cross member 1'7.

- The main drive-Wheel 33 is held in place on shaft 30 by collars 34 attached to the shaft on each side of hub 35 of the wheel. The rim 36 of the drive-wheel 33 is extended to one side to form a flat interior peripheryunobstructed by the spokes. Between hub 3-5 and'the' clutch-member 37 is journaled on shaft 30. Member 37 carries shoes 38 arranged to engage the interior periphcry of rim 36, each of said shoes being held by arms 39 pivotally attached thereto by joints 40 and passing through apertures 41 in the laterally-projecting portion 42 of member 37. For thepurpose of taking up some of the strain between each shoe 38 and member 37, a guide 43 is attached to projcting portion 42 upon whichthe slide 44 of the shoe is movable. Adjacent to member 37 on shaft 30 is splined an axially-movablesleeve 45 upon which is held by tongue-and-groove construction a circumferential ring Rods or links 47 are connected with sleeve 45 by joints 48 and to arms 39 by joints 49.

To one of standards 31 is attached a retaining device comprising projecting arms 50, one above and one below shaft 30, said arms being braced apart by a stay 51, and

forked ends of a rod 56 which leads toward the roar of Y the machine and is connected at its rear end with an operating-lever 57. Lever 57 has a hand-controlled pawl 58 which is cooperable with a fixed ratchet-seg ment 59, whereby the lever is held in desired position.

By operation of lever 57 sleeve 45 is moved to cause the shoes 38 toengage or be disengaged from rim 36, the shoes being thrown against the rim when the sleeve is moved toward the main drive-wheel and released therefrom when the movement is in opposite direction.

At or near eachend of shaft 30 is a fixed clutch-member 00, with which a clutch-member 61 loose upon said shaft is arranged to be cooper-able. Each member 61 is formed with an elongated hub 62 which has thereon a secondary drive-wheel 63, and a circumferential ring 64 is held loose on said hub by'tongue-and-groove construction.

Attached to each outside standard 31 and projecting outwardly is a retaining device comprising arms 65, one

I 'nected at or near the joints the forked ends of a rod 70. Each rod leads and is attached to an operating-lever 71, which has a hand-controlled pawl 72 cooperable with a hired ratchet-segment 73, whereby the lever is held in desired position. By movement of a lever 71 and its connections with ring64, the clutch-members 60 and 61 are engaged or disengaged to throw a secondary drive-wheel 63 into or out of operation. The secondary drive-wheels 63 are connected by belts 74 with wheels 75, one attached to each of the supportingwheels l9 and 20. 5

. Rotatably mounted in brackets 22 in rear of axle 21 is a shaft 76, having an arm 77 thereon which is pivotally connected with a link 78 which leads to an operatihg sex ess.

"lever 79. Lever 79 has a hand-controlled pawl 80- thereon cooperable with a fixed ratchet-segment 81. i

I Art or about the center of shaft 7G is a rearwardlycxtcnding bellcrank 82, to which is pivotallylconnecteda shackle 83, which in turn is pivotally connected with a tongue 84 of a plow-frame 85.

Plow-frame 85 comprises a front cross-member 86 to which tongue 84 is'connect ed, and beams 87"extending rearwardly' therefrom and having down-turried portions 88 to which any suitable plow elements 89, such as moldboards shown in the drawings, or disks, etc., are connected. Diagonal member 90 and crossqnernbers 91 and 92 connect and brace bcams87. A trailing plow-frame is thus formed.

To the rear end of land-side beam 87 is attached a' caster-wheel 93 to "support the rear part of the plow frame 85. The caster-wheel is journals-d on the lower end of the trailing portion 94 of spindle 95, and the spindle is journaled in the bearing 96 secured to the beam. A collar 97 is secured to spindle above bearing 96. Besides holding the spindle in the bearing collar 97 cooperates to control the swing of the casterwheel. Forthis purpose the collar is formed on the side 'opposite the wheel with a recess 98, and at approximately ninety degrees from each side of said recess with lugs 09. A spring-controlled latch secured to hearing 96 normally seats in recess 98 and holds the casterwheel in substantially the line of draft, In turning the plow, latch 100 is released from recess 98 by foot-controlled link 101, when the caster-wheel is free to swing in either direction, the swing being limited by engage ment'oi latch 100 with one or the other of lugs 99; and, when the turning movement is completed, and the caster-wheel again trails in the line of draft, the latch will be returned to recess 98 by action of its spring.

Between and parallel with beams 87 is a bifurcated member 102 connected with and supported by crossmembers 92 and'91. Between the parts of bifurcated member 102 is held a slidable block 103.- The forward part of block 103 is formed with a rearwardly-ovorlap- 405 ping lip or lug 104, and oppositely disposed thereto is a pinion 105 carried on a steering shaft 106 journaled in block 103. Attached to the main frame is a cogged arc 107 which is operable between pinion, 105, with which it meshes, and lip 104, which holds it in mesh 110 with said pinion. The engagement of lip 104 with are 107 also serves to maintain the proper relation between the main and plow frames Attached to beams 87,

and interposed therebetween and arc 107, are antifriction rollers 108, which are arranged to sustain strain between the mainframe and the plow-frame and to permit movement of said frames with respect to each other. A steering-wheel 109 is attached to shaft 106,

and a seat 110 for the operator is attached to the rear end of member 102.

The steering-wheel, the operating-levers hereinbefore described, and the controlling means of the motor are in easy reach of the operator on the seat.

I When it is desired to turn the machine at the end of a furrow, or at other times, the'secondary drive-wheel 1 on the side to which the machine is to be turned is thrown by its operating-lever out of operation, and the machine is carried around by the other secondary drive-wheel actuating its supporting-wheel, in an obvious manner. The plows in the ground and the opse1,os1

eration of the arc and pinion also assist in theesfirning movement. The turning movement being completed, the idle secondary drive wheel is again thrown into operation.

in making a long turn, the clutch-members of one of the secondary drive devices may be brought tightly together, and the clutch-members or the other secondmy drive device brought together so as to be allowed to slip more or less as desired, to drive its supportingwheel with less speed than that on the other side.

Further, the machine is steered without cooperation of the supporting-wheels by means of the operation by the operator of the pinion infmesh with the cogged are,- thus serving to swing the trailing frame and guide the implement. v

The plow-frame is tilted by up or down movement of the bell-crank caused by movement of the operatinglever connected with its shaft. The slight forward or aft movement of the plow-frame incident to this operation is allowed for by the sliding block carrying the steering-pinion.

The main frame is raised or lowered on the land-side supporting-wheel by movement of the cranked end of l the axle on that side caused by actuation of the operating-lever' connected therewith.

. After the motor is started, the driving mechanism is put into or thrown out of operation by movement of the clutch coiiperable with" the main drive'wheel.

Joints 4O permit'the shoes to take the proper set against the main drive wheel-rim, and joints 49 connectin'g arms 39 and rods 47 and joints 48conn'ectingv rods 47 and sleeve 45 permit the requisite axial movement of said sleeve.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. Ida plow-carriage, the combination with supportingwheels, of a single drive-shaft, a main drive-wheel loose on said driveshafflmeans whereby motion from main drivewheel is applied to and released from said drive-shaft, secondary drive-wheels loose on said driveshafit and operntively connected with said supporting'wheels, and means associated with each secondary drive-wheel and independent of said main drive-wheel whereby motion from said drive-shaft is applied to and released from saidsecondsry drive-wheels.
